Blue Impulse (ブルーインパルス, Burū Inparusu) (currently 11 Squadron 4th Air Wing, previously 21 Squadron 4th Air Wing) is the aerobatic demonstration team of the Japan Air Self-Defense Force (JASDF). The team was founded in 1960 as a team of six F-86 Sabres. They changed mounts to the Mitsubishi T-2 in 1980 and then to the Kawasaki T-4 in 1995. They are based at Matsushima Air Base, which was heavily damaged by the 2011 Tōhoku earthquake and tsunami.

History

The first unofficial Japanese aerobatic team was formed in 1958 at Hamamatsu Air Base, flying Mitsubishi-built North American F-86F Sabres without a special colour scheme, disbanded after four demonstrations.

In 1959 the USAF Thunderbirds visited Japan and inspired JASDF commanders to establish an official aerobatic team. In 1960 the new team was formed at Hamamatsu airbase flying five F-86Fs of 2nd Squadron, with three of the pilots coming from the 1958 team.

The first demonstration of the "Tenryū" team, (named after the Tenryū River near the air base), was on 4 March 1960 at Hamamatsu, the name was found to be hard to pronounce in western languages, so the team was renamed Blue Impulse. The aircraft were equipped with smoke generators using five different colours for each aircraft: white, red, blue, green and yellow and painted in silver, light blue, blue and pink; on the leader's aircraft, the blue is replaced by gold. Later, in 1961, all five aircraft received a special paint scheme of overall white with blue flashes.

In 1964, Blue Impulse performed at the opening of the 1964 Summer Olympics in Tokyo, drawing the Olympic rings in the air with coloured smoke. In 1970, at the opening of Expo '70 in Osaka, the team drew "Expo '70" in the air.

In February 1982, after 545 air demonstrations, Blue Impulse replaced the Sabres with Mitsubishi T-2 trainers, performing their first show with the new aircraft was on 25 June 1982 at the team's new Matsushima airbase.

At Expo '90 in Osaka, Blue Impulse performed at the opening event and drew the "Expo '90" logo in the air.

The team's last performance with the Mitsubishi T-2 was in December 1995, after 175 demonstrations with these aircraft. The new Blue Impulse aircraft became the Japanese-built Kawasaki T-4 trainer, and the first show with these aircraft was on 5 April 1996.

In 1997, the team made their first foreign debut at the Nellis Air Force Base air show in Nevada, USA.

In 1998 Blue Impulse performed at the Winter Olympics in Nagano, Japan.

Blue Impulse also performed at the 2002 FIFA World Cup; on 4 June 2002, they performed at the opening of the Japan versus Belgium match.

On March 11, 2011, Matsushima Air Base, where Blue Impulse had been based, sustained heavy damage from the Tohoku earthquake and tsunami. Because on the day before, the aircraft and crew had travelled to Ashiya Air Base in Fukuoka to perform at the opening ceremony of the Kyushu Shinkansen, the team escaped damage from the disaster. While the crew continued to be based in Matsushima to aid in recovery efforts, they were required to travel to other bases for flight training while Matsushima underwent repairs.

On March 30, 2013, the Blue Impulse fully returned to Matsushima Air Base following the completion of repairs and anti-tsunami measures.

The USAF Air Demonstration Squadron ("Thunderbirds") is the air demonstration squadron of the United States Air Force (USAF). The Thunderbirds are assigned to the 57th Wing, and are based at Nellis Air Force Base, Nevada. Created 70 years ago in 1953, the USAF Thunderbirds are the third-oldest formal flying aerobatic team in the world, after the French Air Force Patrouille de France formed in 1931 and the United States Navy Blue Angels formed in 1946.

The Mitsubishi F-2 is a multirole fighter derived from the General Dynamics F-16 Fighting Falcon, and manufactured by Mitsubishi Heavy Industries and Lockheed Martin for the Japan Air Self-Defense Force, with a 60/40 split in manufacturing between Japan and the United States. The basis of the F-2's design is the F-16 Agile Falcon, an unsuccessful offer by General Dynamics to provide a low-cost alternative for the Advanced Tactical Fighter (ATF) competition. Production started in 1996 and the first aircraft entered service in 2000.

The Kawasaki T-4 is a Japanese subsonic intermediate jet trainer aircraft developed and manufactured by the commercial conglomerate Kawasaki Heavy Industries. Its sole operator is the Japan Air Self-Defense Force (JASDF), in part due to historic restrictions on the exporting of military hardware. In addition to its primary training mission, the T-4 has been used by the JASDF's Blue Impulse aerobatic team as well as liaison duties with most fighter units. The first XT-4 prototype flew on 29 July 1985, while the first production aircraft was delivered during September 1988.

The Japan Air Self-Defense Force, JASDF, also referred to as the Japanese Air Force, is the air and space branch of the Japan Self-Defense Forces, responsible for the defense of Japanese airspace, other air and space operations, cyberwarfare and electronic warfare. The JASDF carries out combat air patrols around Japan, while also maintaining a network of ground and air early-warning radar systems. The branch also has an aerobatic team known as Blue Impulse and has provided air transport in UN peacekeeping missions.

All Nippon Airways (ANA) Flight 58 was a Japanese domestic flight from Sapporo to Tokyo, operated by All Nippon Airways (ANA). On 30 July 1971, at 02:04 local time, a Japan Air Self-Defense Force (JASDF) F-86F Sabre jet fighter collided with the Boeing 727 airliner operating the flight, causing both aircraft to crash. All 162 people aboard the airliner were killed, while the Sabre pilot, a trainee with the JASDF, freed himself from his airplane after the collision and parachuted to safety. This incident led to the resignation of both the head of Japan's Defense Agency and the JASDF chief of staff.
